Answer:

Step-by-step explanation:

Use the cos law.

c^2 = a^2 + b^2 - 2*a*b*Cos(C)

Givens

a = 9 cm

b = 6 cm

C = 73

Solution

c^2 = 9^2 + 6^2 - 2*9*6 * Cos(73)      Multiply 2*9*6 by Cos(73)

c^2 = 81 + 36 - 108 * 0.2923              Combine

c^2 = 117 - 31.57                                   Subtract

c^2 = 85.43                                          Take the square root of both sides

c = 9.24
